Too many?

Ok, I have a 20 gallon planted tank. 6 Green tiger barbs, 4 regular tiger barbs. I have two HOB filters. One rated for a 30 gallon, the other for 15 (Used when firing up the QT tank). I would like to put some Corys in there. I have shelter and a small cave dug out that I think they would find rather nice. Now I know corys like friends so I couldn't just get one or two, which means I'm probably starting to over fill this tank. Am I asking too much? If so, is there another bottom dweller I should look into?

The the calculator (adadvisor) in my signature to determine if the filters and tank will work with your stocking idea.

Knowledge is fun(damental)

A 75 gal with eight Discus, fake plants, and a lot of wood also with sand substrate. Clean up crew is down to just two Sterba's Corys. Filters: continuous new water flow; canister w/UV, in-tank algae scrubber!! Finally, junked the nitrate removal unit from hell.

Your regular Tiger Barbs are too big for that tank. They also can be very territorial(leading to aggression) toward other species especially in a small tank like that. Lastly, Tigers are best kept in large schools which cannot be done in that size tank.

Hmmmm... well that is problematic. Right now I have no other tank I could get. I have only the four regular tiger barbs and everything I read said they would school just fine with the green tigers. If I forgot the cory's and just left it as barbs would they manage?

The types of tigers is not the issue, The greens are simply color morphs of the regular ones. They are the exact same species, Same goes for the albino ones also.

The issue is too many fair sized moderately aggressive fish in too small of a space, Extra filtration doesn't remedy this.

They get too too large keep suitable numbers in a 10G:

Gas mileage isn't everythingOIIIIIIIOLack of planning on your part does not constitute an emergency on my part.Why pretend there are no stupid questions? Actually, There are many stupid questions: "Should I drink this bleach?" Is just one example.
Having said that, Just because it's a stupid question doesn't mean that it shouldn't be asked. It's better to know.A warm beer is better than a cold beer. Because nothing is better than a cold beer, and a warm beer is better than nothing.

Having said that, You might notice that directly above the video I posted I mentioned a 10G tank, I have no idea how that got in my head,

If you do this, Nothing else can go in that tank IMO.

Ah, well 850R, I knew they were the same fish, I just read a post wrong that seemed to suggest the greens didn't get quite as big as their normal colored brothers. Yes it is a 20 gallon high and I will hold off putting anything else in the tank until I can find a different home for the barbs. I am quite partial to the barbs, are there other barbs (besides tigers) that would be more suitable to my size?
